Wireless communication apparatus having dynamic transmission bandwidth allocation mechanism and dynamic transmission bandwidth allocation method thereof

Abstract

The present disclosure discloses a dynamic transmission bandwidth allocation method having dynamic transmission bandwidth allocation mechanism used in a wireless communication apparatus is provided that includes the steps outlined below. Interference information and transmission ability information of remote wireless communication apparatuses is retrieved. A predetermined transmission bandwidth range that includes resource units is set. The remote wireless communication apparatuses are allocated in the predetermined transmission bandwidth range to generate an allocation result. Whether the allocation result satisfies resource unit allocation criteria is determined. When the allocation result does not satisfy the resource unit allocation criteria, the predetermined transmission bandwidth range is shrunk to another allocatable transmission bandwidth range to determine whether the allocation result satisfies the resource unit allocation criteria. When the allocation result satisfies the resource unit allocation criteria, the remote wireless communication apparatuses are allocated according to the allocation result to perform communication thereto through a communication circuit.
